. Application August 13, 1940 Serial No. 352,432 1 Claim, (Cl. 131+206) Our invention relates to improvements in tobacco smoking pipes, and the primary object of the present invention is to provide a smoking pipe embodying cooperating features of construction in such an arrangement that the smoke is cooled and rid of noxious substances before it reaches the mouth of the smoker, and whereby the charge of tobacco burns more evenly and requires less relighting.

Other important object and advantages of our invention will be apparent from-a reading of the following description taken in connection with the drawing, wherein for purposes of illustration we have shown a preferred embodiment of our invention. I i

In the drawing- Figure 1 is a general side elevational view illustrating embodiment of the present invention in a conventional appearing smoking pipe.

Figure 2 is a bottom plan view of Figure 1.

Figure 3 is a fragmentary enlarged longitudinal sectional view taken substantially on a line 3-3 of Figure 2, and disclosing the interior arrangements. 2

Referring in detail to the drawing, the numeral 5 generally designates the smoking pipe as a whole which consists of a bit 6 having a reduced terminal portion '1 snugly fitting in a conforming socket 8 formed in the free end of the tubular stem 9 which projects from the bowl [0. The bowl It has a conventional form of tobacco burning chamber II which differs from the conventional arrangement by being located at a greater than ordinary height above the stem 9 so that the bottom I2 of the chamber is spaced above the upper wall of the longitudinal substantially cylindrical passage l3 which extends from the inner end of the socket 8 to a point beyond the vertical center of the tobacco chamber, as indicated by the numeral M. an axial vertical opening l5 which is axially aligned with a larger threaded opening [6 formed in the bottom wall of the stem 9. Threaded in the opening I6 is a plug H of suitable metal or non-metallic material and this plug is provided with a frustro-conical countersink l8 to The tobacco chamber l2 has receive the frustro-conical head IS on the screw 20, the upper part of the frustro-conical opening being threaded to threadably accept the threaded shank portion of the screw so that when the screw is in place with the head thereof in the frustro-conical recess l8 the upper part of the shank extends into the opening l5 in the tobacco bowl chamber and is in concentrically spaced relation tothe sides of the opening I 5.

The screw is provided with a vertical 1ongitudinal passage 22 which opens through its upper'end, which is normally substantially flush with the bottom of the tobacco chamber 12 and the lower end of this passage. 22 opens into a transverse passage 23 which isformed in the shank of the screw andopensthrough both sides thereof at a point about midway the upper and lower walls ofthe pass-agel3 in the stem 9, all as clearly shown in Figure 3 of the drawing.

* The bit 6 has inserted in the bore thereof for a'considerable distance as indicated by the numeral 24 the relatively small'diameter tube 25' which is of suitable metal or non-metallic material and extends in concentrically spacedrelation to the walls of the passage l3 and has the left hand end thereof beveled as indicated by the numeral 26 and located in spaced relation to the adjacent side of the screw 20, whereby l with a charge of tobacco lit in the chamber H in the bowl of the pipe, drawing by the smoker upon the bit 6 will produce a suction through the tube 25 which is communicated to the passage i3 and through the hole l5 in the bottom of the bowl and through the passages 23 and 22, to the bottom of the charge of tobacco, with the result that smoke is drawn down through the charge of tobacco and passes through the opening l5 and through the passages 22 and 23 through and around and in initimate contact with the screw 20 and its threads, so that noxious material entrained in the tobacco smoke and vapors will be separated out of the tobacco smoke and fall and accumulate in the passage l3, whence'the same maybe easily removed upon removal of the screw and the plug l1, without the use of any special tool. With the noxious elements separated and contained in the passage l3, the smoke will pass around the small tube 25 and in its transit in contact with the tube 25 and in the relatively large air space provided by the passage [3 be cooled and upon entering the beveled end of the tube 25, be further. cooled in its transit through the tube 25 and into the bore 2'! of the bit 6, where the tobacco smoke arrivesin a cool and sweet condition unimpaired by saliva, and products of combustion.

Due to the unique arrangement of the screw and its cooperative arrangement relative to the opening in the bottom of the tobacco bowl,

combustion. As a result of this theory of combustion fewer noxious products of combustion are created and those which are unavoidably produced are in a less objectionable condition.

A corollary to this is that there is a smaller accumulation within, the air coolingpassage I3 of noxious substances, with the final result that there is less cooling work to be done and less separation of tobacco smoke required to bring to themouth of the smoker a dry, cooled, and

cleantobaccosmoke. I v 7 Although we have Ishownand described :herein to limit. the application of our invention thereto, except as may be requiredrby. the scope of the subjoined claim... 3 I

. Having described.thecinvention, what is. claimed as newis: v

A smoking. pipe consistingof a bowl having a stem, said bowl. having a, tobacco chamber having its bottom on a, level above said stem, said stem being formed with a relatively large diameter bore acting as an air cooling passage,

.a preferred embodiment, of our invention, itis to be definitely understood that we .do not desire said passage extendingfrom a point adjacent the rear end of said stem to a point adjacent the far side of and below said tobacco chamber, a bit inserted into the rear end of said air cooling passage, said bit having a bore, a cooling tube inserted in the bore of the bit and extending through said air cooling passage in spaced relation to the sides thereof, said air cooling passage being formed with a clean-outopening in its bottom wall beneath said tobacco chamber and said tobacco chamber being formed with a substantially centralized smoke opening substantially axially aligned with said clean-out opening, said cooling tube having its front end terminating rearwardly of the smoke opening, and aplug fitting said clean-out opening, said plug having a reduced shank rising therefrom and extending into said smoke opening in spaced relation to its sides, said shank havingan axial bore opening through its upper end, said shank further having a transverse bore located in said air cooli g passage and havingcommunication with the lower end of said axial bore, said transverse here being in axial alignment with the tube and disposed adjacent the front end of the tube, said plug comprising .a disk threaded into said clean-out opening, said disk being formed with a vertical threaded bore and said reduced shank having external threads engaged with said threaded bore, and means to turn said shank relative to said plug to vertically adjust the shank.
